OILING DEVICE.

Specification of Iletters Patent. I Patented Sept. 24, 1912.

Application filed November 23, 1911. Serial No. 661,885.

To all whom it may concern:

Be itknown that we, J ACOB W.-F. BERRY.

and JOHN MACON, citizens of the United States, residing at St. Louis,State of Missouri, have invented certain new and useful Improvements inOiling Devices; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to iii-sh, and use thesame.

Ourinvention relates to new and useful improvements in oiling devicesand more particularly to an oiling device, by means of which a quantityof oil may be forced, when desired, to the bearings of an engine. Theobject of our invention is to provide a receptacle for containing asupply of oil and means associated therewith for forcing.

a quantity of said oil to the bearings of a engine.

Other objects and advantages of our inmade clearly apparent in thespecification and pointed out in the claims. a

In the accompanying drawing we have shown the preferred form which ourinvention may take.

The drawing shows a longitudinal sectional view through our completedevice.

teferring to the drawings, in which similar reference numerals designatecorresponding parts throughout the several views, 1 is a receptacle,which is preferably circular in cross section, and which is open atoneend and provided with a reduced opening 2 at its opposite end. The openend of said receptacle s adapted to benormally closed by means of acover 3. The cover 3 is proiided with a preferably centrally disposedaperture 4, through which a rack 5 is adapted to extend. The inner-endof the rack 5 is secured to a plun er 6, which is adapted,

as hereinafter described, to force the lubricant contained by thereceptacle 1 through the aperture 2. The cover 3 is also provided with arearwardly extending bracket 7, to the rear end of which is pivotallysecured a gear wheel-8, adapted to mesh with said rack In order that-thegear 8 may be rotated when desired so that the rack 5 may be the upperportion of the receptacle 1. One

end wall of the cylinder 9 is provided with cut off for the opening 2when the piston 17 suitable operating a centrally disposed aperture 10,around which is formed a sleeve 11. The sleeve 11 forms a bearing for arod 12, which is secured at its inner end to a piston head 13. Thepiston head 13 closely fits within the cylinder 9 and is adapted to benormally held in the position shown in the drawing, by means of a coiledspring 14 disposed between one end wall of the cylinder and one face ofthe piston. The outer end of the rod 12 is provided with a pawl 15adapted to engage the teeth of the g an wheel 8.

The opposite endof the cylinder 9 is provided with an opening 15, inwhich is adapted to be secured a pipe 16 for the admission of a suitablefluid such as air or steam.

The reduced outlet opening 2 is secured to and in engagement with an oilcylinder 37, in which is slidablyimountedL a piston head 17 Thepiston'l? is normally in the position shown in the drawing. Said pistonhead is provided with an upwardly} extending portion 18, whichis adaptedto act as a is forced out of the position shown inv the drawings, ashereinafter more clearly described. The opposite end of the cylinder 37is provided with a plurality of openings 19 in which are secured oilsupply pipes 20 adapted to conduct oil to the bearings of an engine. Thepiston head 17 is rigidly connected to a piston rod 2 1, whichextendsthrough the upper endof the cylinder, it being understood that asuitable packing gland 22 is provided for said rod 21. The rod 21 alsoextends throu h the lower end of a cylinder 23, a suitab e packing gland24 being provided. The upper end of the rod is rigidly connected to apiston .25, which isjnormally held in the position shown by means of acoiled spring 26 interposed between said piston and the lower end of thecylinder 23. The upper end of said cylinder.

23 is provided with an opcning'27, in which 100 is secured a pipe,28 forthe admission of a fluid such as air or steam. The pipes 16 an air maybeadmittedto the'c linders 9 and 23, when desired.

The valve 29 consists of acasing and a rotatable member 30 havingcommunicating ways 31, '32 and 33therein. As shown in 110 28 areextended and con-" nected to a suitable operating valve "29, by means ofwhich the operatingiluid such as 9 5 casing 29 is provided with an inletopening 35 adapted to receive the end of a pipe extending from asuitable operating fluid supply tank.

When it is desired to force a quantity of oil to the bearings oftheengine with which our device is associated, the valve is operated soas to bring the ways 31 and 32 into communication with the inlet opening'35 and the pipe 16, respectively. The operatunder pressure, will beadmitted by pipe 16 to the end of cylinder 9 and consequently the piston13 will be forced toward the 9p posite end of said cylinderagainst theaction of the coiled spring 14.. This movement of the piston 13 willresult in causing the pawl 15 to rotate the gear wheel 8. The movementof the gear 8 will force the rack 5 inwardly so that the piston 6 willplace the quantity of grease contained in the recep tacle 1 underpressure and force a quantity thereof through the outlet opening 2 andinto the cylinder 37.

The cylinder 37 is of such a size as to hold a quantity of oilsuflicient to properly lubricate the bearings of the engine to which thesame is connected. When the. cylinder 37 has been filled, as justdescribed, the valve .29 is returned to initial position, allowmg thecylinder 9, to exhaust and then is operated so that the ways 31 and 32are brought into communication with the inlet opening 35 and the pipe28, respectively, so that the operating fluid will be admitted to theupper end of the cylinder 23. The operating fluid will force the piston-25 to the opposite end of the cylinder agalnst the action of the coiledspring 26. At the same time the piston 17 will be moved downwardly tothe lower end of the cylinder 37 and will force the quantity of greaseor lubricant contained therein through the pipes 20 to the bearings ofthe engine to which said pipes are connected.

It will be understood that when the 'piston 17 is moved downwardly, thegrease under pressure in the receptacle 1 will be prevented from fillingthe upper portion of the cylinder 37 by the cut ofi 18.

When the operating fiuid is cut offfrom the cylinders 9 and 23, it willbe understood that the coiled springs 14 and 26, respectively, willreturn their pistons 13 and 25, respectively, to initial position sothat when it is desired to force an additional quantity 7 of oil to thehearings of the engine the above described operation is repeated.

\ 'The receptacle 1 is adapted to contain a a large omentit of heavygrease or other lubricant, which is adapted to be placed under ingfluid, which it will be understood is pressure and forced therefrom. Itis uni necessary and impractical to place the con: tents of thereceptacle under sufficient pressure to force the same directly .to thebearings, so that in addition to the receptacle 1 and its controllingmeans, we find it desirable to employ a smaller receptacle or cylinderadapted to contain a quantity of grease or lubricant suificient for oneoiling, and also employ means for forcing the grease therefrom to thebearings of an engine. 7

From the foregoing description it will be seen that we have provided adevice adapted to contain a quantity of grease or other desiredlubricant and adapted, when desired,

to forcea quantity thereof to the bearings of the engine.

While We have described the preferred form of our invention, we desireit to be understood that certain modifications may I be made thereinwithout departing from the spirit and scope of our invention.
